Statusline issue together with `Rykka/riv.vim`

[DerWeh]

I am currently using gina.vim to show the branch in vim-airline/vim-airline. There seems to be however a severe conflict with ReST files if I use Rykka/riv.vim.

I get the error message

Error detected while processing function gina#component#repo#branch[1]..gina#core#get[33]..<SNR>78_get_from_bufname[1]..<SNR>78_get_from_path:
line    2:
E716: Key not present in Dictionary: new(path)

The minimal init.vim is

let g:vimdir = expand('~').'/.config/nvim'
call plug#begin(g:vimdir.'/plugged')
Plug 'vim-airline/vim-airline'
Plug 'lambdalisue/gina.vim'
Plug 'Rykka/riv.vim'
call plug#end()


call airline#parts#define_function('gina', 'gina#component#repo#branch')
let g:airline_section_b = airline#section#create(['hunks', g:airline_symbols.branch,'gina'])

I am currently using NVIM v0.3.1-1-g489d32f2b, previously used NVIM v0.2.3-1-gd6f9d1df0 giving the same error.

Reproduced. I'll investigate.

" vim -u ~/.vim/vimrc.min
call plug#begin(expand('~/.config/nvim/plugged'))
Plug 'lambdalisue/gina.vim'
Plug 'Rykka/riv.vim'
call plug#end()
set statusline=%{gina#component#repo#branch()}

Workaround

@DerWeh I found a workaround. Call gina#core#get() prior to Rykka/riv.vim.

call plug#begin(expand('~/.config/nvim/plugged'))
Plug 'lambdalisue/gina.vim'
Plug 'Rykka/riv.vim'
call plug#end()

" Call 'gina#core#get()' (or anything) prior to 'Rykka/riv.vim'
call gina#core#get()

set statusline=%{gina#component#repo#branch()}

Positive case (nvim -u ~/.vim/vimrc.min test.txt)

Note: It seems the result of echomsg added are not shown (:messages shows only above message). Because the code is called in statusline?
